Characters

While she cares for her sister Kana, she maintains a certain distance from others. What will she see through in this case?
A college student and the younger twin. With a bright and friendly personality, she hits it off with people she just met. She is a woman of action who moves to verify things herself.

A 25-year-old man. The son of the villa's owner and the child of the chairman of the global corporation "GUNGNIR GROUP." Raised in a wealthy environment, he is a realist who hates trouble.
